rare earth magnets- safe for use around batteries?

[dDubs]

Hey Vapers,
I am finishing a box mod I've made- 2x14500s(in parallel), radio shack project box, horn switch, and a couple LEDs. The cover for the box is held on by four screws, and since the batteries and master on/off are inside the box, securing it with screws is not an option. I picked up some rare earth iron boron somethin-or-other magnets to hold the cover on. They are teeny tiny cubes, like maybe .5mm, and the closest magnet position to the batteries is about 2-4mm(I'm adding a pic but not sure how well you will be able to see them, they are the tiny little silver squares in the bottom corners, I haven't put the top ones in yet). Are they going to affect or cause any problems with the batts?
Thanks,
Dave

I have the same idea and am curious as well

Neodymium mags are used as battery spacers to convert flat tops into pseudo-button-tops. No worries with mags on or near batteries, or used in a circuit.

ETA: I use neo mags soldered to wire leads to charge odd batteries that I don't have a dedicated holder for. Comes in real handy for 18500s since there doesn't seem to be a 18500 battery holder in the entire universe.

Neat idea with the charger!

FYI: TheTrustfire charger I picked up at MadVapes (don't recall model ATM) charges everything from 16340s to 18650s.

Hmmm have you looked lately? I think this is one. I've seen a few others.

That is for 18650's, he said 18500's.

I also use them as battery end connectors and use them as switches with voltage running through them. No problems and the mod is holding up fine

OOPs!!!! I could have sworn it said 18650. Never mind...
